Sonic's gone to plaid in the latest TAS by marzojr. It starts from a savestate to take advantage of Hyper Sonic from the beginning of the game. (For more details, see the note below and the run's comments.)
WARNING: The awesomeness of Hyper Sonic may damage your eyes or trigger seizures in susceptible people.
Note: This movie begins from a save state from the end of regular mode in order to access Hyper Sonic from the beginning of the game. There is no other way to access it outside of a hack. We normally do not accept movies which begin from a save state.
